    "abstract": "We present numerical results on the capacities of two-qubit unitary\noperations for creating entanglement and increasing the Holevo information of\nan ensemble. In all cases tested, the maximum values calculated for the\ncapacities based on the Holevo information are close to the capacities based on\nthe entanglement. This indicates that the capacities based on the Holevo\ninformation, which are very difficult to calculate, may be estimated from the\ncapacities based upon the entanglement, which are relatively straightforward to\ncalculate.",
